Abstract: A tank has a generally prismatic shape, and is capable of containing a pressurized gas. The tank comprises a composite shell, which has fibrous reinforcements and a matrix extending continuously over the six faces of the prism and delimits a sealed internal cavity comprising a plurality of open cells. The tank comprises continuous fibrous reinforcements extending into and bonded to the composite shell and further extending through the internal cavity between two opposite faces of the tank. The tank is advantageously integrated into the floor of a vehicle, in particular to the structure of an aircraft.

Abstract: A method for producing a composite tank is disclosed. The tank has a continuous fiber reinforcement, a prismatic shape, and a thickness “e” for the storage of a pressurized gas in an internal cavity of the tank. The tank comprises fibers extending between two non-contiguous faces of the tank through the internal cavity. The method includes: (i) obtaining a prismatic fibrous preform having a thickness “e” comprising three-dimensional continuous reinforcements throughout its thickness; (ii) impregnating an outer layer of the preform with a polymer over a thickness of less than ¼ of the thickness “e” so as to constitute a composite outer shell extending over all faces of the prism; and (iii) forming a sealed layer constituting an inner lining, having a thickness of less than 1/10th of the thickness “e” between the outer shell and the fibrous network contained in the cavity of the tank.
